ITEM 1. SECURITY AND ISSUER

This Amendment No. 2 amends the Schedule 13D filed on August 1, 2008 (such initial filing, the "Original Filing") by Citadel Investment Group, L.L.C. ("CIG"), Citadel Limited Partnership ("CLP"), Citadel Equity Fund Ltd. ("CEFL"), Citadel Investment Group II, L.L.C. ("CIG-II"), Citadel Holdings I LP ("CH-I"), Citadel Derivatives Group LLC ("CDG"), Citadel Holdings II LP ("CH-II"), Citadel Advisors LLC ("Citadel Advisors"), Citadel Derivatives Trading Ltd. ("CDT") and Kenneth Griffin ("Griffin" and, together with CIG, CLP, CEFL, CIG-II, CH-I, CDG, CH-II, Citadel Advisors and CDT, the "Reporting Persons") relating to the shares of common stock, $0.01 par value per share (the "Common Shares"), of Huntsman Corporation (the "Issuer"), as amended by Amendment No. 1 to Schedule 13D filed by the Reporting Persons on September 2, 2008 ("Amendment No. 1" and, together with the Original Filing, the "Prior Filing"). Capitalized terms not defined herein shall have the meaning given to them in the Prior Filing.
 
ITEM 4. PURPOSE OF TRANSACTION
 
Item 4 of the Prior Filing is amended by deleting the seventh paragraph thereof and adding in its place the following:
 
On September 8, 2008, the Reporting Persons and certain other institutional investors (the "Other Backstop Payment Parties" and, collectively with the Reporting Persons, the "Backstop Payment Parties") delivered a letter (the "Backstop Payment Commitment Letter") to the Issuer intended to facilitate the consummation of the Proposed Merger. In the Backstop Payment Commitment Letter, the Backstop Payment Parties agreed to make certain backstop payments to the Issuer if the Proposed Merger is consummated on the terms provided in the current merger agreement on or prior to November 2, 2008. These cash payments would be added to the combined balance sheet of Huntsman and Hexion at the Closing of the Proposed Merger with Hexion. In the Backstop Payment Commitment Letter, the Backstop Payment Parties severally agreed to make backstop payments to the Issuer totaling $230,226,116 (the Reporting Persons would be responsible for $80,080,000 of this amount). The Backstop Payment Commitment Letter is intended to be a legally-binding obligation of the signatories, subject to the conditions described therein. A copy of the Backstop Payment Commitment Letter is attached as Exhibit 99.7.
 
To become binding on the Backstop Payment Parties, the Backstop Payment Commitment Letter must be accepted by the Issuer on or prior to September 11, 2008. The Backstop Payment Parties' several obligations in the Backstop Payment Commitment Letter would then be subject to the requirement that the Issuer receive similar commitments from the Huntsman Participants such that the aggregate amount of all backstop commitments is at least $416,460,102. According to a Schedule 13D amendment filed by the HMP Equity Trust and others on September 8, 2008, the Huntsman Participants have made a backstop commitment to the Issuer of $186,233,986. The Backstop Payment Parties' several obligations under the Backstop Payment Commitment Letter would also be subject to the requirement that the Issuer concludes it is not practical to cause Hexion on a timely basis to accept the CVR financing offered by the Proposal Letter and the Commitment Letter, which remain outstanding. The Backstop Payment Commitment Letter further provides that if any Backstop Payment Party purchases CVRs (or makes an equity or similar investment in the combined company, as may be agreed with Hexion), and the other Backstop Payment Parties and the Huntsman Participants are given the opportunity to purchase CVRs or make an equity or similar investment on the same terms and conditions, then each Backstop Payment Party's commitment to make backstop payments will terminate.
 
 
CUSIP No. 447011107
Page 13 of 16 Pages
 
As a result of the potential arrangements described in the Proposal Letter, the Commitment Letter, and the Backstop Payment Commitment Letter, the Reporting Persons may be deemed to have formed a "group" with some or all of the Other Investors, the Other Backstop Payment Parties, and/or the Huntsman Participants for purposes of Rule 13d-5(b)(1) promulgated under the 1934 Act; however, the Reporting Persons disclaim membership in a group with the Other Investors, the Other Backstop Payment Parties, and the Huntsman Participants with regard to the Common Shares of the Issuer.
 
ITEM 5. INTEREST IN SECURITIES OF THE ISSUER
 
(a)
Number of shares: 18,654,710 shares1

(c) The table attached hereto as Exhibit 99.8 sets forth the transactions effected by the Reporting Persons in the Common Shares (and options to purchase or sell such Common Shares) since Amendment No. 1. Such transactions resulted from the exercise by third parties of listed option positions previously acquired in open market transactions.
 
(d) Not applicable.
 
(e) Not applicable.

2 According to the Issuer's Form 10-Q, filed with the Securities and Exchange Commission on August 7, 2008, there were 234,457,138 Common Shares issued and outstanding as of August 4, 2008.
